IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128(about 3.4×1038) addresses. IPv6 also implements new features that simplify aspects of address assignment (stateless add...
IPv6 Address Type: Unicast An IPv6 unicast address is an identifier for a single interface on a single node. A packet that is sent to a unicast address is delivered to the interface identified by that address. The Cisco MDS SAN-OS supports the following IPv6 unicast address type...
Interface IDs used in aggregatable global unicast and other IPv6 address types must be 64 bits long and constructed in the modified EUI-64 format. Interface IDs are constructed in the modified EUI-64 format in one of the following ways: F...
I'm having trouble understanding IPv6 addresses. In IPv4 the CIDR slash notation means what subnet the address is in. But a /48 in IPv6 does not mean subnet. I have no idea what it means. For instance I've seen the address 2001:0:1:5::1/64, and I have no idea what the /64...
1) one of the feature of ipv6 is auto-configuration. With auto-configuration, a ipv6-device can configure itself with IP address without relying on dhcp server.But what about other parameters for e.g dns? So with ipv6 the need for dhcp is not completely removed am i correct? 2) Let...
Understanding IPv6 EUI-64 Bit Address SunilKhanna Level 1 05-16-2012 03:46 AM - edited 03-01-2019 04:48 PM Introduction Extended Unique Identifier (EUI), as per RFC2373, allows a host to assign iteslf a unique 64-Bit IP Version 6 interface identifier (EUI-64). This feat...
Dynamic Address Assignment IPv6 prides itself as a protocol that supports many dynamic plug and play functionalities. As a result, there are multiple ways to assign IP addresses in IPv6. This guide will go over two methods of IPv6 address
实际上,这个概念类似于ipv4中,当DHCP分配失败时自动生成的169.254.XXX.XXX这样的地址,凡是源地址或目的地址中含有link-local address的报文,路由器都不应当转发它。这样的报文只能在一个LAN中互通。 <IPV6的地址类型> 可分为三大类: 1、单播地址 2、组播地址 ...
